Razor 无法识别 asp- 标签助手

Question

I have following HTML code

<a asp-action="index">Demo</a>

the asp tag is not recognized by Visual Studio 2022

and when I build and run the solution the asp tag is not translated into the html code

There are no warnings, errors or JavaScript errors.

I copied the Views folder from .NET Core 2.1 MVC into the .NET 6 Core MVC project. The Index.cshtml file has BuildAction = Content property as other files in the View folder.

What might went wrong, why the tag helper is not translated?

Answer 1

I finally figured it out. The reason was that I had file ViewImports.cshtml but it should be named _ViewImports.cshtml . I don't know how that happened, but in this discussion https://social.msdn.microsoft.com/Forums/en-US/f9d42158-3bb6-490c-a59f-579eedeb060f/razor-not-rendering-tag-helper?forum=aspdo.netcore the another user had the same issue
